+# 业务线程池(v2.3.0-rc.2)
+
+::: tip
+
+业务线程池是 <Badge text="2.3.0-rc.2" type="tip" vertical="middle"/> 中新增的。
+
+:::
+
+## 配置内置业务线程池
+
+```yaml
+jt808:
+  # Netty 线程池
+  msg-processor:
+    executor-group:
+      thread-count: 2
+      pool-name: 808-msg-processer
+      max-pending-tasks: 128
+  ## 业务线程池(指令服务器 和 附件服务器共用)
+  msg-handler:
+    enabled: true
+    core-pool-size: 64
+    max-pool-size: 128
+    keep-alive: 1m
+    max-pending-tasks: 256
+    daemon: true
+    pool-name: 808-handler
+```
+
+## 替换内置业务线程池
+
+要替换内置的业务线程池，请提供一个 `Jt808ServerSchedulerFactory` 类型的 `Bean`。
+
+```java
+
+@Configuration
+public class SomeConfigurationClass {
+
+    @Bean
+    Jt808ServerSchedulerFactory jt808ServerSchedulerFactory() {
+        return new Jt808ServerSchedulerFactory() {
+            @Override
+            public ExecutorService getMsgHandlerExecutor() {
+                // 这里返回自定义线程池
+                return null;
+            }
+        };
+    }
+
+}
+```
